3 claims; (ci. iii-sil m l 'Myd invention relates to posts and piles and more particularly to means for protecting the `PON/i011 f the pile" below the surface of the water T or ground. T l T I, T T

i T An important object ofmyinvention is the I provisionof means" forprotecting the surface of f l piles from deterioration and from the ravages of destructive organisms in a simple and inexpensive manner. l l T T A further object Tof myinvention is the provision `of `pile protecting means which can Tbe readilyTappliedT to the pile and which doesnot require Ta substantial amount of head room in which to Work. l

i Other `objects and advantages of my invention ing description. T T T In the accompanying drawing which forms a part of this specification and wherein like char- 20 acters of reference denote like or corresponding parts throughout T Figure lT isT aT side elevation of a" pile having my invention applied thereto, T

Figure 2 is a horizontal sectionalview on the line 2--2of Figure 1, T I Y `Figure 3 is a vertical sectional lviewon the 1in@ 3- 3 irrigare 2, and l m Figure 4 is a perspective View of a portion Toi T theprotective casing and clamping members. In the drawing, wherein for the purpose of illustration is shown aT `preferred embodiment of mninventionthe numeral I Il designates a pile supporting the structure II `at a point above 3,. the surface of the water,` and having its lower end 1 will be apparent during the course of the followembedded in the ground below the Water. My`

l 1 `improvement consists in a generally cylindrical casing of metal `or other suitable material formed ting relation, as indicated in Figure 2, they form a cylindrical casingof substantially greaterdiameter than the pileabout which they are to be placed, having a generally T-shaped rail at each side formed by the abutting tongues I3. T In order o to securely clamp the sections together I provideT a series of clamping runners or channels I4 which are Tof generally rectangular cross-section with one ofT their sides slotted to receivethe abutting l walls of thetongues I3. `When the tongues I3 55 are in close relation, the clamps I4 are telescopedT j 1. The assembled casing may then be forced into the ground below the water, and is of a length sections are togetherwith the tonguesIS in abuttherewith,` fitting closely about the tongues and securing the sections in assembled position, Tas best seen in Figure 2. The clamps I4 are formed in suitablelengths and slid down over the tongues from their tops. IT T i T Spacing fingers I5 are struck out of thel lower l edge of the casing sections I2 and extend inwardy 1y in a horizontal position to a point adjacent but spaced from the pile, as indicated in Figure 2.T These fingers insure the proper spacing of 10 the casing sections from the pile. While the pile and casing are illustrated as circular in cross-section, the pile may havek some other configuration and the casing will conformto the general shape ofthe pile. T` Tl I 15 In use the two `casing sections are. placed about the pile and the clamps I4 forced ldown over the tongues I3, one at a time, preferably `until the tongues are completely covered, as inFigure `ing is of a diameter considerably greater than the pile and the fingers I5 insure an annular 25 `space between the pile and casing. This space is lled with a suitable plastic material I 6 which is physically and chemically repellent to destructivemarine life. A mixture of sand and asphalt or tar and sand will produce the desired results. This material below waterremalns in a somewhat plastic state and will consequently follow the con- 'formation of the pile and casing. T i

An important feature of my `invention is the fact that the protective casing and filling may be` applied to a pile where there is very little head room available.` The casing sections are placed in the water and can be moved laterally into position about the pile. The clamping sections are made in sections having a length of a 40 few inches up to several feet, depending on the head room available between the top of the casing and the structure II. They may be placed on the tongues one at a time and require only a iewTinches of head room when made in short lengths. The casing and its lling provide protection against the ravages of the usual marine organisms which destroy the piles, and will last indefinitely.

While I have shown and described the p-referrea` embodiment of my invention it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my inven- T T tionor the scope of the sublioined claims. 55

Having-thus described my invention, what I claim and desire to protect by Letters Patent is:

1. Protecting means for piles comprising a longitudinally split casing adapted tosurround `a pile and capable of being moved laterally into position about the pile, cooperatingl projections extending along the edges ofl the split portiony of the casing, a clamping member adapted to telescopically receive the projections, said clamping member bein'gdivided into a` plurality ofrelatively short sections, said casing being ofxgreater diameter than the pile whereby an annular space is' formed between the pile and'casing, spacing ngers carried by the casing and extending in wardly towards the pile, and a lling of plastic material arranged in the and casing.

2. Pile protecting means comprising a casing adapted tol surround the pile in' spaced relation therewith, said casing being divided longitudinalspace between the pile ly into two sections, longitudinally extending'` anged tongues Iextending along thev edges of said sections, channel shaped clamping members adapted .to slidably receive said tongues, said clamping members being divided into a plurality'` of relatively short sections, and a filling material arranged between the casing and pile.

r3. Pile protecting means comprising `a casing `adapted to surround the pile yin spaced. relation' therewith, said casing being' divided longitudinally into two sections, longitudinally extending flanged tongues extending along the edges of said sections, channel shaped` clamping members adapted to slidably receive said tongues, said clamping members being divided into a pluralityl of relatively short sections, spacing fingers eX- pile,"and-aff1ll`ing material arranged between the casing and pile. y
